First, my apologies that it took so long to update the OP. Busy and then crazy times intervened and I forgot. I respond below and have edited the OP.

Done. Used this comment for citation in the bibliography at the end of the OP.

Added this, too, with citation to you.

Those didn't exist in USDM market, might be a CDM chassis/trans? Were they 35mm (small bore) like the 90-91 EX Sedan's or 40mm (big bore) like the 92-00 USDM? Quaife never got their info correct.

Thanks for the correction. Nice catch.

You have sold all of that inventory by now, I guess, yes?

That number is from a cited source, not my personal counting. I have not counted teeth on my old DX (D16y7) transmission (yet). I will at some point and keep this question in mind.

My guess is that both gear shafts would probably drop in with minimal modification, but I don't think the Fit is appropriately powered to go from a 4.3 FD to a 3.2.

This is interesting, but I wonder... Doesn't the Fit have the transmission on the driver side of the engine? The gears would be cut with opposite rotation in mind, no?
